Title: Semiconductor device for photodetection use
Inventor: KATAOKA MASAYUKI
IPC: H01L31/02
Filed: 1988-09-13
Abstract: PURPOSE:To contrive the simplification of an assembly process by a method wherein a light-transmitting hole is formed in a circuit board and a photodetector is mounted on the board by a flip chip method in the form of making the photodetecting part face on this hole. CONSTITUTION:A light-transmitting hole 2 is formed in part of a circuit board 1 in the form of penetrating this board 1 on the inside and outside of the board 1. A photodetecting part 4 of a photodetector 3 is faced on the hole 2 and the photodetector 3 is mounted on one surface of the board 1 by a flip chip method. It is important that a high verticality is realized between the part 4 of the photodetector 3 and irradiation light to this part 4, but as the photodetector 3 is mounted by the flip chip method, a high parallelism can be easily secured between the part 4 and the board 1 at the time of this mounting. Accordingly, in case the board 1 is supported on a mother board 8 by mounting leads 12, 12..., the above verticality can be enhanced by paying attention to securement of the parallelism between both of the part 4 and the board 1.

Title: Manufacture of semiconductor device
Inventor: ARAI CHIHIRO
IPC: H01L21/316
Filed: 1991-08-14
Abstract: PURPOSE:To not unduly increase the number of processes and shorten a bird's beak by a method wherein, after patterning of an oxidation-proof mask film formed via a pad oxide film on a semiconductor substrate, a polycrystalline silicon film is formed on the entire surface of the semiconductor substrate and thermally oxidized. CONSTITUTION:A pad oxide film 2 is formed on a semiconductor substrate 1, and thereafter an oxidation-proof mask film 3 composed of Si3N4 is formed on the pad oxide film 2. Next, the region where a selectively oxidized film of the pad oxide film 2 is formed is etched. Next, a polycrystalline silicon film 7 is formed to form a selectively oxidized film 4 by thermal oxidization. Thus, it is possible to consume an oxidizing agent and prevent the formation of bird's beak as a result of infiltration of the oxidizing agent into the region between the oxidation-proof mask film and the silicon semiconductor substrate by subjecting the polycrystalline silicon film outside the oxidation-proof mask film to oxidation by means of the oxidizing agent. Accordingly, the bird's beak can be made shorter.
